Thanks for reaching out! kata-containers does not expose any MMDS to 
guest applications at the moment. There were discussions using it for 
simple container data transfer (such as kubernetes secret map etc.) but 
it is not implemented.

I cannot tell if there is any customer using it internally (If so, it is 
time to speak out, please!). Other than that, I'd like to say that 
please feel free to make breaking changes and we'll be glad to use the 
refined APIs when needed.

Cheers,
Tao
